Specificzttion forming pzut 0f Letters Patent N0. 214,576, di'tt0d April 22, 1879; application fi1O.

February 10, 1879.

T0 all whom z't may concem:

Be it known that I, FERDINAND MEYROSE,

0f the eity 0f St. Louis, in the State of Missouri, l1zwe invented a new and useful Improvement in Lanterns, of which the following is Et full, clear, and exact deseription, referenee being had t0 tl1e aceompanying drawings, forming part 0f this speeifieation. 1

My improvement belongs to that dass of lzmterns in whieh mir is suppliecl t0 the burner through pipes extending upwa-rd toward the bail, so tl1at the swinging of the lantern will 110t eause au air-eurrent in lt. The formation of such current results in the extinguishment of the flamme.

My inventiou'eousists in providing the upper ends 0f tl1e deseribecl air-tubes Witl1 a shel= terecl mouth, which prevents the air entering in a strong eur1ent, whatever vmy the lzmter'u maybe swung. Praetieally, when the lautem is swung, th e centrifugal influenee 011 the air in the tubes counterbala-nces the smne 011 tl1e air withiu the lzunp, aud the air surrounding the fizune is not agitated t0 any disadvzmtageous extent.

In the drawings, Figure 1 is oneh:tlf in elevation ancl one-half in 2LXlill seetion. Fig. 2is a perspeetive view, sl1owing tl1e inside of. one 0f tl1e a-ir-tube mouths.

A is the oil-vessel. B is tl1e base er f00t. Above tl1e oil -vessel 2u1d surrounding the lower partof tl1e burner is an annular air ehamber, O, communieating with the interior 0f the dome D 0f the Immer by orifices 01 in the w2 tlls of tl1e d01ne. E is the wiek-tube, furnished at the upper end With defleetor 01 win gs e, t0 prevent any direet eurrents from the 01ifiees d t0 the base 0f the fiame. F is a perforated (lisk, which rests 011 tl1e dome of the burner, ztnd whieh has an upturned marginal fizmge, f, surrouncling the l0wer end 0f the globe G, whieh lzttter is sustainetl by the plate er disk F. Tl1e upper end 0f the globe is held by the lower edge, h, of the eap H, which surrounds seid end.

I I are air-tubes, attaehed Ll7 their lower ends to tl1e walls of the air-ehamber (J, 2u1d communieating With S2tid ehztmber 2Lt op posite sides. These tubes extend upward outs1de the globe G, and have at the upper ends mouths J, 0pen upon the side toward the glcobe. The mouth l1"ils top and bottom flanges, j anal j, parallel with eael1 other, 01 nearly so. The endsj' 0f the mouths have an inturned direetion, being 011 planes radial to the globe, 01 thereabout, ancl aet as defleetors t0 prevent violent eurrents 0f air entering the mouths i 0f tl1e -air-tubes when the lautem is swung up- 0n the bail K.

L is a ring seeured 130 the tops 0f the airp ipes I, am]. surrounding the upper end of the gloloe. by a hinge on one side and a catch, M, 011 the other. 'lhe eatel1 holds the c2tp firmly down 011 the globe, 2u1c1 seeures tl1e latter in plane.

'lhe eatch M ancl the hinge with whicl1 the eap is eonneeted to the ring L are attaehed 130 theflange N, surrounding the cap. 'lhis flange serves t0 proteet the globe from min, more especially tl1e upper and hotter part, but is not a neeessary feature to the lautem.

I am aware that lanterns have already been constructed wherein tl1e air-tubes eomn'1unica-te with a. eontinuous fing 2 tt the top of the globe, and I am also aware tl1at it is contemplated to Gut away portions 0f seid ring. Neither construction, however, would possess tl1e advanteges seeured by the use 0f the flanged mouths shown and described by me, by which tl1e tubes are protected fro1m sudden blasts 0f air. Such eneireling ring I d0 110t claim; but

VVhat I elaim as my invention, aml desire 130 secure by Letters Patent, is-

In combination with the Immer D E, nirehamber C, in communieation with lt, and upwardly-extencling air-tubes I, the mouths J,

constructed ancl arranged snbstantially es set forth.
